C# 如何更改菜单悬停颜色

如何更改Windows应用程序菜单的悬停（鼠标悬停）颜色

C#中的任何方法？

或

使用Windows API（DllImport）有任何方法吗？

如图所示：

您正在使用MenuStrip类。可以覆盖其渲染器。这里有一个例子，请选择你自己的颜色

public partial class Form1 : Form {
    public Form1() {
        InitializeComponent();
        menuStrip1.Renderer = new MyRenderer();
    }

    private class MyRenderer : ToolStripProfessionalRenderer {
        public MyRenderer() : base(new MyColors()) {}
    }

    private class MyColors : ProfessionalColorTable {
        public override Color MenuItemSelected {
            get { return Color.Yellow; }
        }
        public override Color MenuItemSelectedGradientBegin {
            get { return Color.Orange; }
        }
        public override Color MenuItemSelectedGradientEnd {
            get { return Color.Yellow; }
        }
    }
}

控件其他颜色元素的其他属性。

要更改鼠标在边框上的颜色（在项目上），请使用以下命令：

public override Color MenuItemBorder  
{
    get { return Color.Green; }
}

您还可以使其透明（不可见）：

我也有类似的问题，我浏览了很多文章，很多论坛，但没有找到我问题的完美答案。我不仅遇到了下拉菜单元素悬停的问题，还有背景和总体布局的问题，以及如何以编程方式添加子元素的问题。然后我发现了如何在Stackoverflow论坛中轻松定制MenuStrip，但是我仍然遇到了下拉列表的问题。然后我自己发现ContextMenuStip具有实现目标的特性。将任何MenuStrip添加到ContextMenuStrip作为下拉菜单是很容易的。哦，是的：它的优点是你不需要使用任何特殊的组件

因此，步骤如下：

    public class submenuColorTable : ProfessionalColorTable
    {
        public override Color MenuItemSelected
        {
            get { return ColorTranslator.FromHtml("#302E2D"); }
        }

        public override Color MenuItemBorder
        {
            get { return Color.Silver; }
        }

        public override Color ToolStripDropDownBackground
        {
            get { return ColorTranslator.FromHtml("#21201F"); }
        }

        public override Color ToolStripContentPanelGradientBegin
        {
            get { return ColorTranslator.FromHtml("#21201F"); }
        }
    }

    public class LeftMenuColorTable : ProfessionalColorTable
    {
        public override Color MenuItemBorder
        {
            get { return ColorTranslator.FromHtml("#BAB9B9"); }
        }

        public override Color MenuBorder  //added for changing the menu border
        {
            get { return Color.Silver; }
        }

        public override Color MenuItemPressedGradientBegin
        {
            get { return ColorTranslator.FromHtml("#4C4A48"); }
        }
        public override Color MenuItemPressedGradientEnd
        {
            get { return ColorTranslator.FromHtml("#5F5D5B"); }
        }            

        public override Color ToolStripBorder
        {
            get { return ColorTranslator.FromHtml("#4C4A48"); }
        }

        public override Color MenuItemSelectedGradientBegin
        {
            get { return ColorTranslator.FromHtml("#4C4A48"); }
        }

        public override Color MenuItemSelectedGradientEnd
        {
            get { return ColorTranslator.FromHtml("#5F5D5B"); }
        }

        public override Color ToolStripDropDownBackground
        {
            get { return ColorTranslator.FromHtml("#404040"); }
        }

        public override Color ToolStripGradientBegin
        {
            get { return ColorTranslator.FromHtml("#404040"); }
        }

        public override Color ToolStripGradientEnd
        {
            get { return ColorTranslator.FromHtml("#404040"); }
        }

        public override Color ToolStripGradientMiddle
        {
            get { return ColorTranslator.FromHtml("#404040"); }
        }
    }

menuStrip.Renderer = new ToolStripProfessionalRenderer(new LeftMenuColorTable());

你需要一张彩色桌子

您必须在菜单上使用它

MenuStrip上的ToolStripMenuItems必须具有ContextMenuStrip作为下拉列表

通过ToolStripMenuItems.Items[？].DropDownItems函数，您可以轻松地操作显示为下拉元素的子元素

1.-颜色表：

    public class submenuColorTable : ProfessionalColorTable
    {
        public override Color MenuItemSelected
        {
            get { return ColorTranslator.FromHtml("#302E2D"); }
        }

        public override Color MenuItemBorder
        {
            get { return Color.Silver; }
        }

        public override Color ToolStripDropDownBackground
        {
            get { return ColorTranslator.FromHtml("#21201F"); }
        }

        public override Color ToolStripContentPanelGradientBegin
        {
            get { return ColorTranslator.FromHtml("#21201F"); }
        }
    }

    public class LeftMenuColorTable : ProfessionalColorTable
    {
        public override Color MenuItemBorder
        {
            get { return ColorTranslator.FromHtml("#BAB9B9"); }
        }

        public override Color MenuBorder  //added for changing the menu border
        {
            get { return Color.Silver; }
        }

        public override Color MenuItemPressedGradientBegin
        {
            get { return ColorTranslator.FromHtml("#4C4A48"); }
        }
        public override Color MenuItemPressedGradientEnd
        {
            get { return ColorTranslator.FromHtml("#5F5D5B"); }
        }            

        public override Color ToolStripBorder
        {
            get { return ColorTranslator.FromHtml("#4C4A48"); }
        }

        public override Color MenuItemSelectedGradientBegin
        {
            get { return ColorTranslator.FromHtml("#4C4A48"); }
        }

        public override Color MenuItemSelectedGradientEnd
        {
            get { return ColorTranslator.FromHtml("#5F5D5B"); }
        }

        public override Color ToolStripDropDownBackground
        {
            get { return ColorTranslator.FromHtml("#404040"); }
        }

        public override Color ToolStripGradientBegin
        {
            get { return ColorTranslator.FromHtml("#404040"); }
        }

        public override Color ToolStripGradientEnd
        {
            get { return ColorTranslator.FromHtml("#404040"); }
        }

        public override Color ToolStripGradientMiddle
        {
            get { return ColorTranslator.FromHtml("#404040"); }
        }
    }

menuStrip.Renderer = new ToolStripProfessionalRenderer(new LeftMenuColorTable());

2.-在菜单上使用它：

    public class submenuColorTable : ProfessionalColorTable
    {
        public override Color MenuItemSelected
        {
            get { return ColorTranslator.FromHtml("#302E2D"); }
        }

        public override Color MenuItemBorder
        {
            get { return Color.Silver; }
        }

        public override Color ToolStripDropDownBackground
        {
            get { return ColorTranslator.FromHtml("#21201F"); }
        }

        public override Color ToolStripContentPanelGradientBegin
        {
            get { return ColorTranslator.FromHtml("#21201F"); }
        }
    }

    public class LeftMenuColorTable : ProfessionalColorTable
    {
        public override Color MenuItemBorder
        {
            get { return ColorTranslator.FromHtml("#BAB9B9"); }
        }

        public override Color MenuBorder  //added for changing the menu border
        {
            get { return Color.Silver; }
        }

        public override Color MenuItemPressedGradientBegin
        {
            get { return ColorTranslator.FromHtml("#4C4A48"); }
        }
        public override Color MenuItemPressedGradientEnd
        {
            get { return ColorTranslator.FromHtml("#5F5D5B"); }
        }            

        public override Color ToolStripBorder
        {
            get { return ColorTranslator.FromHtml("#4C4A48"); }
        }

        public override Color MenuItemSelectedGradientBegin
        {
            get { return ColorTranslator.FromHtml("#4C4A48"); }
        }

        public override Color MenuItemSelectedGradientEnd
        {
            get { return ColorTranslator.FromHtml("#5F5D5B"); }
        }

        public override Color ToolStripDropDownBackground
        {
            get { return ColorTranslator.FromHtml("#404040"); }
        }

        public override Color ToolStripGradientBegin
        {
            get { return ColorTranslator.FromHtml("#404040"); }
        }

        public override Color ToolStripGradientEnd
        {
            get { return ColorTranslator.FromHtml("#404040"); }
        }

        public override Color ToolStripGradientMiddle
        {
            get { return ColorTranslator.FromHtml("#404040"); }
        }
    }

menuStrip.Renderer = new ToolStripProfessionalRenderer(new LeftMenuColorTable());

3.-以编程方式向菜单元素添加ContextMenuStrip

        ContextMenuStrip CMS = new ContextMenuStrip()
        {
            Renderer = new ToolStripProfessionalRenderer(new submenuColorTable()),
            ShowImageMargin = false
        };

        ToolStripMenuItem TSMI = new ToolStripMenuItem("Button name")
        {
            BackColor = sampleMenuItem.BackColor,
            ForeColor = sampleMenuItem.ForeColor,
            Font = sampleMenuItem.Font,
            Margin = sampleMenuItem.Margin,
            Padding = sampleMenuItem.Padding,
            Size = sampleMenuItem.Size,
            TextAlign = sampleMenuItem.TextAlign,
            DropDown = CMS 
        };

        menuStrip.Items.Add(TSMI);

4.-操纵子元素

在这里，您可以操作（例如：添加）下拉菜单的元素。颜色、大小和其他属性仅以这种方式用于测试。可以使用常量或不同的值。（“i”是要添加子项的菜单按钮索引）

在我的案例中，结果如下：
